If the level 1 oemcrypto library loads and initializes, but has the
wrong version or does not have a valid keybox, then the level 3
fallback is used. However, in those cases, the level 1 was not
terminated properly. This caused a resource leak on some platforms.
With this CL, in OEMCrypto_Initialize, the level 1 library Terminate
is called if its Initialize was called and the level 1 library will
not be used.

AUPT is revealing a crash when destructing WVDrmPlugin due to
multi-threaded contention over the session map. As a fix, we are now
protecting access to the map via a mutex.

On arm64, some devices are having random issues that probaby relate to
a stale instruction cache. This code change flushes the cache for
pages that are going to be made executable.

This CL just updates the integration guide. In particular, the
following clarifiaction is made about usage tables:
The sentence:
When the session using this key is closed, the entry in the table will
be marked as inactive.
is replaced by
After the session using this key is closed, the application will
request that the entry in the table will be marked as inactive.
This should make it clear that OEMCrypto should not automaically
deactivate usage entries. This behaviour is already verified by unit
tests.

When falling back to L3, release requests were failing. Information
requesting falling back to L3 is passed along when the session is opened.
Licenses however are released using the key set ID and information
requesting fallback to L3(CdmClientPropertySet) at that point is
unavailable. The release was actually attempting to release a license
at the default security level which is incorrect.
In addition, the mac keys were not being setup correctly and the release
message was signed with keys derived from the license request and not the
response. Both these issues have been addressed and unit tests added
to track release of offline licenses and usage reporting scenarios.

It is an error for the key control block to have a nonzero replay
control flag and a null pst. This CL adds unit tests to
oemcrypto_test to verify that oemcrypto checkes this. A unit test is
also added for verifying that an offline license has a valid nonce the
first time it is loaded.
It also updates the reference implementation (mock) to check that the
pst is not empty when the replay control flag is nonzero.
It also updates the level 3 implementation to check that the pst is
not empty when the replay control flag is nonzero.
This change is compiled into the arm library, but because of
compilation errors, is not included in x86 or mips.
